The posts set up on the passes by the NWMP were effective in the short term, as the provisional boundary was accepted, if grudgingly. In September 1898, serious negotiations began between the United States and Canada to settle the issue, but those meetings failed. The treaty of 1825 had been drawn up in French, and the 1903 British advocates discussed the exact meaning of words like "/coast", "/strip" and "/crest". The maps of
George Vancouver, which were used as a fixing line by the commission of 1825, showed a continuous line of mountains parallel to the coast — however, the mountain range is neither parallel to the coast nor continuous. Finally, in 1903, the
Hay–Herbert Treaty between the United States and the United Kingdom entrusted the decision to an arbitration by a mixed tribunal of six members: three Americans (
Elihu Root, Secretary of War;
Henry Cabot Lodge, senator from Massachusetts; and
George Turner, ex-senator from Washington), two Canadians (
Sir Louis A. Jette, Lieutenant Governor of Quebec; and
Allen B. Aylesworth, K.C., from Toronto), and one Briton (
Baron Alverstone). Aylesworth had replaced
John D. Armour, the Chief Justice of Ontario, who died in London on July 11, 1903, while working on the boundary commission. All sides respected Root, but he was a member of the
U.S. Cabinet. Canadians ridiculed the choice of the obscure ex-Senator Turner and, especially, Lodge, a leading historian and diplomatic specialist whom they saw as unobjective. The tribunal considered six main points: • Where the boundary began. • What "Portland Channel" meant, and how to draw the boundary line through it. Four islands were in dispute. • The definition of the line from "the southernmost point of Prince of Wales Island to Portland Channel", which depended on the answer to the previous question. • The line from Portland Channel to the
56th parallel north. • The width of the (border or edge), and how to measure it. • Whether mountain ranges existed in the area. The British member Lord Alverstone sided with the U.S. position on these basic issues. The agreed demarcation line was a compromise falling roughly between the maximal U.S. and maximal Canadian claim. The "BC Panhandle" (the
Tatshenshini-Alsek region) was not quite
exclaved from the rest of British Columbia. In 1929, Canadian scholar
Hugh L. L. Keenlyside concluded, "The Americans, of course, did have the better case." He judged that most of the tribunal's decisions were fair. Regarding the key issue of the islands in the Portland Channel, however, This was one of several concessions that Britain offered to the United States (the others being on fisheries and the Panama Canal). It was part of a general policy of ending the chill in Britain–U.S. relations, achieving rapprochement, winning American favor, and resolving outstanding issues (
the Great Rapprochement). ==Aftermath==
